ABSTRACT:
A concrete curing blanket includes a layer of absorbent material and a layer of impervious material bonded to the absorbent material layer in face-to-face relationship at intermittent locations such that the impervious material layer between the intermittent locations can lift away from the layer of absorbent material in response to air bubbles rising through the layer of absorbent material. The intermittent bonding locations may take the form of a pattern or may have a random occurrence. The absorbent layer of material is a hydrophilic nonwoven fabric and the impervious material layer is a film.
